MCO-138 revert "18663 - should be internationalized"

This reverts commits c6b9451f8bd719c72335ccb2759feb1655055933 and 6d52920470a6135ac1368111d9ddfe3c50264bee.

The i18n based around the i18n gem was incomplete and a little hard to deal
with.  For now we're pulling this implementation out for the stable series and
will revisit it in a topic branch until we have something more mature.
